Custom IML Labels (In-Mold Labels)

IML Labels

Formed to Fit, Built to Stay

IML labels are not applied after production — they’re embedded into the container itself, giving you ultra-durable graphics that won’t scratch, wrinkle, or peel under any condition.

Material Options

We use only injection-mold-compatible films that meet the highest industry standards:

• White PP Film – Opaque, vibrant base for full-color prints
• Clear PP Film – Seamless, transparent finish for a clean, product-forward look
• Metallic IML Film – Chrome or gold shine for premium or luxury lines
• Recyclable PP – Sustainable, mono-material label compatible with eco-packaging

Sizes & Shapes

We tailor every IML label to your container’s mold:

• Wraparound, front-panel, lid-top, or multi-panel IML designs
• Cut-to-size with extreme precision for seamless container integration
• Suitable for tubs, buckets, containers, jars, lids, and trays

Printing & Finish Options

All IML labels are printed in high definition using specialized, mold-ready techniques:

• Full-color CMYK or PMS printing
• Matte, gloss, or dual-texture finishes
• Spot UV or metallic ink accents
• Antistatic coating to ensure proper placement during molding

Key Advantages of IML

• No Peeling or Scratching – Label is fused into the surface
• Moisture & Chemical Resistance – Ideal for harsh environments
• High-Speed Automation Ready – Perfect for mass production
• Sustainable – Container and label are a single material, aiding recyclability

Best Applications for IML Labels

IML is preferred in industries where longevity and shelf appeal go hand-in-hand:

• Food & Dairy: yogurt cups, margarine tubs, ice cream containers
• Household Products: cleaning product tubs, wipes, detergent containers
• Industrial Use: paint buckets, lubricant pails, fertilizer containers
• Beauty & Personal Care: creams, powders, lotion jars

The 3Ps of In-Mold Labeling

Presentation

IML delivers high-end, photo-quality branding that becomes part of the product surface.

Protection

When measuring a custom box, there are a few technical specifications that must be considered to ensure proper design, manufacturing, and fit for the product. Here are the major technical things to measure a custom box:

Inside Dimensions (Critical for Product Fit)

• Length (L): The longest side of the box measured inside from one corner to the opposite corner.
• Width (W): The shorter side of the box measured inside perpendicular to the length.
• Depth/Height (D or H): Measured inside from the bottom to the top opening of the box. Always specify that dimensions are given in Length × Width × Height.

Outside Dimensions (Important for Shipping & Storage)

• Measure the outer surfaces of the box including material thickness.
• Outside measurements are used for pallet stacking, warehouse spacing, and shipping compliance.

Material Thickness (Board Caliper)

• The thickness of the packaging material (e.g., corrugated board, rigid stock, cardstock).
• Impacts both the internal usable space and external dimensions.

Flap Measurements

• For boxes with flaps (e.g., mailer or shipping boxes), measure:
• Inner flaps: Ensure they meet in the middle without overlapping too much.
• Outer flaps: Allow proper sealing without gaps.

Tolerances

• Account for manufacturing tolerances (usually ±1/16" or ±2mm depending on material).
• Ensure the product fits without being too tight or loose.

Volume Capacity

• Calculate internal cubic capacity (L × W × H).
• Helps in determining how much space the product will occupy and shipping efficiency.

Product Orientation

• Decide how the product sits inside the box and measure accordingly.
• Orientation affects whether length or width is the primary dimension.

Die-Cut Openings or Windows

• Measure exact placement, height, and width for any cutouts.
• Ensure structural integrity when adding windows.

Printing Bleed & Safe Zones

• Include measurements for:
• Bleed area: Extra space beyond the cut line for printing.
• Safe zone: Inner area where critical text or logos should be placed.

Closure Type & Locking Tabs

• Measure slots, tabs, or locks for boxes with custom closures.
• Precision is required to avoid misalignment during assembly.

Packaging Style

• Folds, creases, and scores must be measured for accurate dieline creation.
• Different styles (e.g., RSC, tuck-end, mailer, sleeve) require specific panel measurements.
